Onion Powder is a beige-coloured powder that is made from fresh onion that has been peeled, dried, then ground to a fine powder.

It is used as a spice to provide an onion flavour in food where you wouldn't necessarily want chunks of onion.

It also provides a quick way to provide onion flavour from dry storage when fresh onion is not available, or, when preparation time in cooking is limited.

Onion powder also provides flavour, without adding bulk or liquid from the onion into the dish being made.

It is also useful in dry rubs, in breads, in DIY dry mixes, and in flavouring soups, sauces and gravies at the last minute.

It is a "real" ingredient; not artificial. Unless it has been adulterated by unscrupulous dealers, it is meant to be pure onion.
